PORTLAND, Ore. – Monte Robin Kaija, Jr., 47, of Portland, was sentenced today to 70 months in federal prison for detonating a small explosive device at a Fred Meyer store in Southeast Portland, and later possessing a homemade metal pipe bomb.

According to court documents, on May 21, 2016, the Portland Police Bureau (PPB) received a report of an individual placing a small pipe bomb made of PVC in an aisle of a Fred Meyer store on SE 82nd Avenue in Portland. Portland Fire & Rescue were dispatched to assist PPB with their response. Kaija detonated the device shortly before police arrived on scene, causing damage to a single aisle. Nobody was injured in the explosion, and Kaija fled. While processing the scene, PPB officers identified several fragments of white plastic PVC pipe, pieces of white plastic PVC end caps, electrical tape, and a granular, power-like substance.

After analyzing the materials collected on scene, the Oregon State Police Lab notified PPB that a DNA profile had been collected from a small piece of electrical tape. The DNA profile was matched to Kaija. On August 31, 2016, PPB officers arrested Kaija in a motorhome on SE 96th Avenue in Portland, and discovered a homemade metal pipe bomb in his motorhome. A certified bomb technician assigned to the Portland Metropolitan Explosive Disposal Unit responded to the scene and rendered the device safe. As a convicted felon, he was not allowed to possess the destructive devices.

Kaija previously pleaded guilty to two counts of possession of an unregistered destructive device in violation of 26 U.S.C. §§ 5841, 5861(d), and 5871 on December 12, 2016. Upon completion of his prison sentence, Kaija will be on supervised release for three years.

The PPB and Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) investigated this case. It was prosecuted by Hannah Horsley and Paul T. Maloney, Assistant U.S. Attorneys for the District of Oregon.
